Iodine monoxide is a binary inorganic compound of iodine and oxygen with the chemical formula IO•. A free radical, this compound is the simplest of many iodine oxides.[1][2][3] It is similar to the oxygen monofluoride, chlorine monoxide and bromine monoxide radicals.
Synthesis
[edit | edit source]Iodine monoxide can be obtained by the reaction between iodine and oxygen:[4]
- I2 + O2 → 2 IO
Chemical properties
[edit | edit source]Iodine monoxide decomposes to its prime elements:[citation needed]
- 2 IO → I2 + O2
Iodine monoxide reacts with nitric oxide:[5]
- 2 IO + 2 NO → I2 + 2 NO2
Atmosphere
[edit | edit source]Atmospheric iodine atoms (e.g. from iodomethane) can react with ozone to produce the iodine monoxide radical:[6][5]
- I2 + 2 O3 → 2 IO + 2 O2
This process can contribute to ozone depletion.[citation needed]
